PRESENTING…

Deep sea deposit composed of finely divided clay material

Derived from the land

Transported by winds and ocean currents

Deposited far from land in the deepest parts of the ocean basin

Especially in mid- latitudes

Red clay found very extensively on the floor of the Atlantic Ocean is specially rich

in iron.

Red clay from sea

Ribbon seaweeds (sp. Laminaria) contain iodine compounds which they obtain by extracting iodide ions from seawater.

This iodine can be extracted from the seaweed by heating it in air to an ash, in which the iodine is present as iodide.

The iodide is dissolved out of the residue by boiling water, the solution filtered and the iodide oxidized to iodine using hydrogen peroxide.

The iodine colours the solution brown at this stage.

Isolating the iodine from the solution can be done by solvent extration, followed by the evaporation of the solvent.

Extraction of iodine from seaweed

Is a loose colloquial term encompassing macroscopic, multicellular benthic marine algae. The term includes of some members of the red, brown and green algae. Seaweeds can also be classified by use (as food, medicine, fertiliser, industrial, etc.).

Minerals from dead sea

The Dead Sea contains some 45,000 million tons of salts rich in minerals.

The Dead Sea contains 26 essential minerals, 12 of the Dead Sea minerals do not exist in any other sea or ocean in the world.

The high concentration causes high density of the water and consequently it is possible to float on it.

A large part of the Dead Sea salts and minerals penetrate the skin and this makes the Dead Sea the only area in the world in which the natural healing

method of climatotherapy is applied for treatment of various diseases.

Limestone formationLimestone formation cascade down the hillside below the site of ancient Hierapolis ( modern Pamukkale in Turkey ).

The city is famous for its continuing geological

transformation.Hot mineral springs issue from the rock in the city, and the water streaming

down the cliffs have deposited limestone in large formations, the

surface of which is made a gleaming white “frozen

cascades”.
